You have a summer job detailing cars. you charge $5 to wash a car, $25 to wax a car, and $2 to vacuum a car. what algebraic expression models the total amount you can earn? if you wash 8 cars, wax 2 cars, and vacuum 6 cars, how much will you earn in all?

algebraic expression models the total amount you can earn .

You earn $102 in total If you wash 8 cars, wax 2 cars, and vacuum 6 cars

Step-by-step explanation:

Let x be the no. of cars you washed

Cost of washing 1 car = $5

Cost of washing x cars = 5x

Let y be the no. of cars waxed

Cost of waxing 1 car = $25

Cost of waxing y cars = 25y

Let z be the no. of cars vacuumed

Cost of vacuuming 1 car = $2

Cost of vacuuming z cars = 2z

Let T be the total cost

So,

So, algebraic expression models the total amount you can earn .

Now we are supposed to find that you wash 8 cars, wax 2 cars, and vacuum 6 cars, how much will you earn in all?

x = 8

y= 2

z=6

Substitute the value in the expressions

Hence You earn $102 in total If you wash 8 cars, wax 2 cars, and vacuum 6 cars

2. 1/4 =2/8
5/8 =5/8
1 hour=8/8
The rule is to add 3/8 every time so the answer would be...
11/8= Thur
14/8 = 1 and 3/4 of hour.

4. 5 - (1, 1/2 + 1, 3/4) =
1/2 = 2/4
1, 2/4 + 1, 3/4 = 2, 5/4 = 3, 1/4
5 (4, 4/4) - 3, 1/4 = 1, 3/4
Glad to Help!
